A new class of negative refractive
index (NRI) transmission line is proposed. Differential operational
amplifiers are used to form the required lumped elements, i.e.,
negative-impedance-converted (NIC) inductors and capacitors. When the gain
of the differential operational amplifiers in the NIC circuits is very large
over the entire frequency band, the equivalent material parameters are
non-dispersive, and the phase response of the new NRI transmission line can
be complimentary to that of a conventional transmission line over the entire
frequency band. As an application example, a broadband 1:4 power divider
based on the proposed NRI transmission line is studied.
